Hi there,

The Batlogger M2 is the new incarnation of the very popular Batlogger M.

Giving you a hand-held detector with all the features of the Batlogger M, but improved.

Now with USB charging and file transfer, a tripod-mounting socket, voice microphone, protected repairable and replaceable microphone, great grip and useful buttons.

Warm Regards,


"Have done 5 transects back to back. Very impressed with performance, and find the ability to upload a transect path to the batlogger to follow a great asset for the unit (saves having follow transect on phone or tablet). The additional environmental info is really useful too." Jon

Batlogger M2
The ideal tool for bat workers
The BATLOGGER M2 is easy to use and provides all the features you need in a bat detector. You can tag recordings during your survey and make voice recordings with additional information, so that it’s the only tool that you need to have with you.
The right recording mode for your survey
Transect or emergence counts? We have the right settings already built in for all your surveys. Just select the mode before you start and you’re ready to go.
Custom profiles can be created for special situations.
Replaceable microphone
Replace your microphone without any tools. The microphone capsule is safe inside its housing and survives drops much better than our previous model.
Rechargeable battery
Don’t worry about replacing batteries or even using disposable batteries.
Want to charge your BATLOGGER M2 in the field using a power bank? No problem.
Use any USB-IF approved USB charger.
Simple file transfer
Copy recordings to your computer while charging your BATLOGGER M2. Thanks to the USB-C connector, you don’t even have to remove the microSD card anymore. But of course you can still use the microSD card for the file transfer if you want to.

Comment from a client:

"My bat detector microphone failed during a dawn survey and knew that I had a group of dusk surveys starting in two days time. I was not in a good place as I did not have a spare, but my equipment was less than a year old.

After my survey I contacted Martin by email and he called me back on the same day, a few hours later, after a quick nap. He told me he did not have a part in stock, but had already contacted the supplier on my behalf.

The next day I received a replacement part, free of charge and express delivered from Switzerland. I thought it was amazing, and could not believe it was resolved so quickly.

Due to Martin's exceptional service I was good to go with the surveys, and I really would like to thank Martin and Wildlife Countryside Services for making the dusk surveys happen."
